It is necessary do this to build Derby 10.1 on any platform. See the
previous thread today concerning that. I thought that is was mentioned
in the build instructions (BUILDING.txt), but maybe not.

This should not be necessary. Could you post the errors you received
trying to build an unmodified source tree?

This should not be the case. Could you also post these errors?

I build on Mac OS X all the time without needing any source
modifications, as it's my primary development platform.

In case it helps, here's my ant.properties:
